Don't you love crucible? Especially when you don't like it because people use overpowered characters like warlocks and Titans, how about the chaperone quest? Ive spent 2 days trying to get the last word crap out of the way but I love how every time I try to get to at least 50 percent, some op Titan shoulder charges me when I'm 10 feet away from it, how about that every time I die I lose about 5 percent of the quest and it doubles! I've read it's supposed to take away 3 percent but it takes away 5 for me! Don't you just love bungie and their stupid chaperone quest where it FORCES you to play crucible just get it :) and I can already tell there's going to be a huge amount of fat sweaty nerds who will comment "oh you are only mad because you aren't good enough to get it"
You only need to have the last word equipped at the end of the game. You don't have to actually use it.
I was having a mare doing it as well, so what I did was use my mida like I normally do. When I did ok or good with like 30 seconds to go in the game I would equip the last word. If I did badly I wouldn't bother.
Took a bit longer, but I completed it in maybe 10 games, maybe less
